Speed, acceleration setting range
The load capacity differs depending on the mounting orientation and the transport speed.
Refer to the selection chart (intro pages 3 and 4) and the specifications chart of each model (pages 1 and 13).
The size and screws lead must be selected.
Check the load capacity
STEP-2
Follow the examples below for the selected product and check if it matches the required tact.
Check the tact time.
